Monitoring and Controlling Boiler Water/Steam Cycle Chemistry
is Hot Topic Hour on Thursday, February 21, 2013
Safe, reliable and efficient operation of steam generating boilers and HRSGs
requires the maintenance of physical and chemical conditions throughout the
water/steam circuit that minimizes corrosion and deposit formation. This is
especially true in the older plants that are predominate in our electricity
production network. Deposition of contaminants, scaling and corrosion are the
cause of many forced outages resulting in lost power generation or product
output costing billions of dollars per year. Frequent blow-downs required
because of excessive contaminants in the water/steam also contribute to lost
production. Inadequate cycle chemistry will cause boiler tube and turbine
blade/disc failures and Flow-Accelerated Corrosion (FAC) throughout the circuit.
The method chosen to control the water/steam chemistry depends on the boiler or
HRSG type, water/steam circuit design, materials of construction, physical
parameters (temperatures, pressures, heat fluxes, etc.) and the operating cycle
of the plant. In all cases, it is essential to be able to measure the key
parameters of the water/steam so that operators are able to properly manage and
adjust the control method (typically chemical addition) to ensure that physical
and chemical targets for the water are achieved.
The following speakers will discuss how to monitor and manage boiler water/steam
physical and chemical properties in order to reduce unplanned outages, reduce
operation and maintenance costs and improve unit economics. The speakers will
describe the instruments and technology available for monitoring water/steam
properties and chemistry with a discussion of capital and operating costs and
their experience with the instruments or technologies. They may also describe
the various control chemicals and technologies available with a discussion of
which particular chemicals or technology is appropriate for specific boiler/HRSG
types and water/steam circuits.
Joe Zimmerman,
Director of Marketing and Power Industry Sales Manager
at Chemtrac Systems, Inc., will present “Continuous Real-Time Corrosion
Product Transport Monitoring using Particle Counter Instrumentation.” The
adverse effects of “particulate” material in steam cycle waters are frequently
seen throughout the power generation process. Steam cycle corrosion products
(transient metal oxides) can lead to deposition and equipment failure. This
presentation introduces basic technologies used for continuous detection of
insoluble particles at very low concentrations. When such monitoring methods are
utilized, real-time corrosion product transport measurement can be implemented
as a potential parameter for controlling the power plant cycle.
Greg Thomas,
Key Account Manager for Nuclear Power at Hach Ultra Analytics,
will present a comparison of the long time standard amperometric technology to
the new optical technology for measurement of low level dO2 in steam
cycle water. The presentation will briefly discuss amperometric and optical
technology for the measurement of low level dissolved oxygen. Performance
comparison data of the two technologies in steam cycle applications will be
presented. Finally, comparisons along with advantages and disadvantages will be
discussed.
David M. Gray,
Senior Product Manager at Mettler-Toledo Thornton, Inc., will present “New
Technology for Monitoring Cycle Chemistry.” He covers online analytical
measurements of conductivity, pH, dissolved oxygen, sodium and silica.
Intelligent Sensor Management incorporates digital sensors with improved
performance, wider rangeability and predictive diagnostics. He will discuss how
these capabilities can improve cycle chemistry monitoring while reducing
maintenance.

U.S. Water Utilities are Embarked on Thousands of Capital Projects
The need to meet new environmental standards, the growing demand for water and
the need to replace obsolete infrastructure are causing U.S. water utilities to
embark on thousands of capital improvement projects. These projects are
tracked in the McIlvaine North American Public
Water Plants and People. (www.mcilvainecompany.com)
Growing demand is why Bay City, Michigan is planning a $60 million regional
treatment plant. Arkansas City, Kansas is planning a new $12 million plant.
Annapolis, Maryland is building a $35 million plant.
Some of the expenditures are to meet new regulations. Clay Center, Kansas,
which has about 4,300 residents, built a $10 million water treatment plant to
clear the water of uranium that can occur naturally in underground aquifers.
The Kansas Department of Health and Environment (KDHE) said of the five
communities with excessive uranium in their drinking water, only two — Timken,
population 75 and a Garden City subdivision with about 860 residents — have not
taken any action to comply with the federal regulations. KDHE said enforcement
action is under consideration for those two communities.
Among the many upgrades, controls have some of the fastest payback. Many
utilities are looking at adding:
• Higher bandwidth (speed and polling rate) communications
• Redundancy
• Cyber Security – DHS, NERC/CIP
• Disaster Recovery Control Center
• Web reporting for internal and customer cities
• Hydraulic modeling and planning data interface
Three (3) classifications of SCADA systems are available:
Commercial-off-the-shelf (COTS) System, Semi-Customer Large Scale (SCLS) System,
and Distributed Control System (DCS).
East Palestine, Ohio is purchasing a System Communication and Data Acquisition
(SCADA) system to monitor the water plant's distribution equipment, including
the two lift stations. The system will allow the department to respond more
quickly in the event of a water leak or equipment malfunction.
Now, only water levels in one of the plant's two storage tanks are monitored
through a land-line telephone system. The current system is costing the village
$400 to $450 a month in utility bills for that tank. The SCADA system would be
completely web-based and cost roughly $200 a month in utility bills. The system
will be cellular-based with seven cellular sites and three radio sites. It will
cost about $61,000 and will monitor water levels and the overall operation of
all water towers, each booster pump and the lift stations, and the information
can be accessed online or through a Smartphone. Currently, there is no way to
monitor the stations except physically.
Suppliers are now offering improved systems with even faster ROI. Yokogawa
Electric released CENTUM VP integrated production control system. Enhancements
include a Field Control Station (FCS), with four times the processing
performance, twice the application storage capacity and five times the control
network throughput of the previous control station.
